Plating Processes and HISAKA Plate Heat
Exchanger
Plating is a crucial modern surface covering technology in which a metal is deposited on a conductive surface. Plating
places an important role in:
* Decorating object
* Corrosion and degradation prevention
* Hardening object
* Alter conductivity
* Minimise friction
Therefore, plating can be used in various industries, ranging from:
i. Common household items and accessories
ii. Automobiles
iii. Computers and communication devices
iv. Precision instruments
v. Aerospace hardware
However, it is crucial to note that the plating materials used in plating process are extremely corrosive as the metals are
either dissolved electrically or chemically. Therefore, plating equipment requires to high corrosion resistance in order to
meet the production requirements.
HISAKA Plates Heat Exchanger is ideal for plating processes because of:
i. High corrosion resistance
ii. Excellent heat exchange efficiency
iii. Accurate temperature control
iv. Enables high adjustment precision
v. Lightweight, compact and ease of maintenance
HISAKA WORKS is a comprehensive and
integrated manufacturer of plate heat
exchangers having the most advanced
production facilities.

HISAKA Plate Heat Exchanger
Structure of a Plate Heat Exchanger (PHE)
Plate heat exchangers (PHE) plates:
- Pressed thin metal plates that have convex and concave wave
patterns (herringbone patterns)
- Made of corrosion resistant materials, such as stainless steel or
titanium
- Perimeter of the plates is sealed with synthetic rubber gaskets
(slit in or glue on method)
Advantages of Plate Heat Exchangers (PHE)
- Suspended perfectly on both upper and lower guide bars
- Fastened and compressed by a fixed and moving frame
Mechanisms:
* Counter current flow of high temperature fluid and low
temperature fluid flowing against each plates. This phenomenon
ensures heat transfer to take place.
* Gaskets ensure that the flowing fluids do not intermix.

1. High-Performance
- Pressed - moulded herringbone patterns enhance heat conduction performance (heat transfer
coefficient), hence able to reduce heat conduction surface area.
2. Lightweight and Compact
- Compressed thin heat transferring plates
- Limited fluid capacity
- Smaller heat transferring surface area
➞ This realizes reduction in installation space,
making installation and maintenance
easier

3. Quick Start - Up
- Limited fluid capacity per unit allows quick
operation start up, and also possible to
correspond to changes in operating conditions with high precision.
4. Excellent Maintainability
- Assembly and disassembly are made convenient by simply removing the fastening bolts
- Maintenance are thereby made easy, even for visual inspections and cleaning

5. Easy Modification of Capabilities
- Flexibility in modifying the heat transferring surface area by
simply increasing or decreasing the number of plates

The fluid flows alternately through the flow path created between each
plate and forms a countercurrent of the high temperature fluid and the low
temperature fluid between every other plate to perform the heat exchange.

PLATING PROCESSES
Bath temperature used during plating process has to be constant in order to prevent plating defects such as low gloss, adherence
inconsistencies, and uneven color distribution.
Corrugated tubes (material: lead) of highly corrosion - resistant materials, electrical heaters, jackets, shell and tube heat exchangers
(material: stainless steel, carbide, titanium and etc) are commonly used to control the temperature of the plating bath. Reasons
being are as follow:
1. Capacities are insufficient for large plating volumes, along with high heat generation
2. High heat transfer capacities require the system to increase in size and installation space
3. Larger unit of highly corrosion - resistant heat exchanger would translate to increase production cost and installation cost
4. Larger volume capacity then translate to difficulties in quality control, especially in terms of temperature control
Plate Heat Exchangers (PHE) are more ideal because of the following reasons:
1. PHE has the same heat transfer capacities
2. PHE is lightweight (only 1/3 of the weight of shell and tube exchanger) and compact (only 1/4 of the installation space required)
3. PHE is more economical even with the installation of highly corrosion - resistant materials
4. PHE offers great flexibility (and hence quality control) to control temperature of the plating tank due to lesser input volume of
plating liquid required
5. PHE also enables quick machine activation due to lesser fluid volume involved; which in turns greatly reduce the operation
time and ultimately save more on operating cost

Plate Heat Exchangers for the Plating Industry
Chrome Plating
Chrome plating is a finishing treatment on a metal surface with either
the usage of electrolytic deposition of chromium anhydride (sargant
bath) or fluorinated chromic acid (fluoride bath) to:
1. Improve decorativeness
2. Increase corrosion
3. Increase wear resistance
However, when chromic acids are concerned, highly corrosion
- resistant plate and gasket materials are needed for optimal
functionality of the heat exchanger.

· Chromic Anhydride (Sargent Bath)
Plate: TP270
Gasket: Fluororubber (EPDM application)
· Fluorinated chromic acid (Fluoride Bath)
Plate: SUS317L
Gasket: Fluororubber (EPDM application)
As fluorinated chromic acid which is highly corrosive in relation to metal
is contained, it is expected that the corrosion resistance life of the plates
will be shorter than in ordinary applications.
Sulfuric Acid Copper Plating
Sulphuric acid copper plating is essential in microelectronic industry
where electronic components are inserted into printed circuit boards
(PCB) and soldered to pads on the opposite side either by manual
assembly or by automated insertion mount machines.
Sulphuric acid also acts as an electrolyte to facilitate plastic plating
processes via strike plating method. The plate material recommended
for this plating process is titanium, as to prevent electrolytic corrosions.

Zinc plating is the most reliable, effective and economical preventative
measure of corrosion and rust by forming a barrier and acting as
sacrificial anode when the barrier is damaged.
Zinc plating can be done in either alkaline environment (zincate
bath) or acidic environment (acidic bath). However, since plating
conducted under acid environment is more effective, titanium plates
are recommended to prevent electrolytic corrosion.
Gasket: EPDM
Similarly, nickel plating is also used to:
1. Improve decorativeness
2. Enhance corrosion resistance
3. Improve wear resistance
Plate heat exchanger functions in electrolytic plating which
precipitates metal nickel by injecting currents in the electrolyte
containing nickel ions.

Tin plating has been used extensively in food industry due to its
non-toxic, ductile and corrosion resistant properties. Consequently,
it is used to protect both ferrous (eg: copper and nickel) and other
nonferrous surface metals.
Similarly, tin plating can be conducted in other alkaline or acidic
environment, yet, it works best under acidic conditions. Therefore,
titanium plate is recommended.
